Getting list of reports a user has access to

Question

Hi,
I'm new to BO and have been trying to figure out a way to get a list of reports a specific user has access to. In reading the documentation in the SDK it appears the only way to do this is to get a list of all reports, loop through them, getting the ObjectPrincipals, looping through that then checking if the objectPrincipal.Name == user.Title.
            foreach (InfoObject report in infoObjects)
                SecurityInfo securityInfo = report.SecurityInfo;
                ObjectPrincipals objectPrincipals = securityInfo.ObjectPrincipals;
                foreach (ObjectPrincipal objectPrincipal in objectPrincipals)
                    if (objectPrincipal.Name != user.Title) continue;
                    if (!sortedList.Contains(report.ID))
                        sortedList.Add(report.ID, report.Title);
This works, but takes over 90 seconds to generate the list of reports I want, as it is looping through all reports in the CMS (120). My logic is telling me there must be a better way to do this, I just haven't found the answer. It appears that calling securityInfo.ObjectPrincipals is what is taking the most time.
Advice, thoughts, suggestions are all appreciated.
Thanks
James

Answer 1

Ok, logging in as a user and getting a list of reports is working well and fast. But how would you recommend getting a list of all users and the reports they are assigned to. Is there a query for that using the relationship functions of Query Builder?
